Medical Marijuana Growers

The Oregon Medical Marijuana Program (OMMP) is responsible for the registration, regulation and oversight of medical marijuana in Oregon, including medical marijuana growers and grow sites. OMMP growers are individuals designated by a patient to produce marijuana for the patient. The patient may designate themselves or another person as their grower.

Information for Growers

Grow site fee

The grow site registration fee is $200.


Growers must pay the grow site registration fee IF they are:

  • Growing for another person; or
  • Growing at a site other than their home; or
  • Growing more than 12 plants; or
  • Transferring excess product to processors or dispensaries.


  • Payment is due when the patient is applying for the first time, renewing their registration, or making a change to designate a new grower.
  • OMMP will notify a grower when a patient submits a new or renewal application that lists them as the grower.
  • The notification will instruct you to sign-in to your online account and pay the grower fee.
  • Online payment can only be made with a credit or debit card.
  • The grower card will not be issued until the grow site registration fee payment is received. If the payment is not received by the due date, the grower and grow site will be removed.
  • The grower card will be mailed to the grower after the grow site registration fee payment is received.
